Water systems can vary greatly in the Scamp trailer depending upon which unit is used. Every trailer has a 12 gallon fresh water tank located under the right side rear bunk. To fill, open the fresh water fill cap at the right rear of the trailer, and use either a bucket or a hose to fill the tank. The tank has an overflow which will emit underneath the trailer when the tank is completely filled. A 3/8” clear tubing connects the water tank to the water pump to the sink faucet. The sink faucet will either be a hand pump or, if the trailer has a 12 volt demand pump, it will be a pressurized system. The hand pump operates by pumping the handle up and down. This pump will occasionally not work if the seals become dry. If this occurs remove the bottom of the pump by unscrewing it (the clear water supply tube will need to be disconnected). When the bottom of the pump is off, two seals will be visible. It is the lower seal that usually will cause the problem. Lubricate this seal with mineral oil. Also, in the lower part of the pump a marble will be visible. This marble seals up the supply hole in the lower part of the pump. If there is a foreign object interfering with this marble the pump will not be able to hold its prime.
Demand pumps are installed on any trailer with a toilet or shower and by special order. Hand pumps are deleted on trailers with a demand pumps. All demand pumps work off the 12 volt electrical system, and are filtered. To operate the demand pump the black switch on the side of the sink cabinet must be on. The sink faucet, toilet and shower are supplied from this pump.

Water supply for the shower and toilet follows the contour of the trailer where the floor meets the wall. Since the Scamp trailer has very little drop from the front to the rear the grey water drains slowly out of the shower area. A 12 volt grey water pump has been installed to remove gray water from the shower area. There will be a black switch to the right of the toilet in a side bath model, and to the left of the shower controls in a front bath model that controls the pump. This pump should be while showering, not left on continually. There is a swinging gate valve installed in-line which prevents grey water from coming forward while traveling. The shower operates by turning water on at the shower valve, left control hot, right control cold. Volume control is on the shower handle itself.
Black water tanks are located under toilet and hold six gallons. Grey water tanks are located under the rear dinette or sleeping area, and hold 26 gallons. Both black and grey water tanks have venting for water displacement and odor. When waste water holding tanks are used they must be periodically emptied. A 10 foot 3” sewer hose is supplied in the hose carrier on the front of the trailer to facilitate this operation. The hose carrier is the white cylinder mounted on the front of the trailer. Remove the sewer hose by unscrewing the cap on either end. Both black and grey water tanks have a termination fitting.
